Research on Silicon Nitride Powder Prepared by Self-propagating High-temperature Synthesis

Zhang Xiangjun, Li Jinfu, Li Guobin, Li Kang (No.52 Institute of China Ordnance Industries, Ningbo 315103,China)  
β-Si3N4 powder was prepared by the self-propagating high-temperature synthesis (SHS) and examined by X-ray diffraction and SEM. It was studied how the following parameters influenced the final product: nitrogen purity and pressure, combustion temperature, diluents content, the porosity, and so on. The experimental results showed that the different type of β -Si3N4 powder with integrated crystalloid structure and smooth surface could be prepared by SHS as long as the parameters be controlled during the reaction,β phase content decreased from the center of the cake to the surface. Because of the existence of the NH4Cl, the reaction involved not only the silicon nitriding mechanism,but also other mechanisms. Considering the combustion temperature,the SHS Si3N4 process involves three mechanisms: low-temperature mechanism, moderate-temperature mechanism, high-temperature mechanism. During the process Si3N4 powder could be introduced as starting raw materia1 in order to control reaction temperature and obtain the desired α content of Si3N4 powder, the porosity of body should be controlled at 30%~70% ,otherwise, SHS reaction would not carry on. The Si3N4 powder with high α content could be prepared when fine silicon metal powder used.
